Preparation of Li-B Alloy and Study of Its Microstructure and Discharge Characteristics

摘要

A Li-B alloy has been prepared using a pretreated amorphous B powder and pure Li ingot as staring materials by continually slow addition of B powder and intensified stirring in the process of melting. The microstructure and the discharge characteristic of the materials have been investigated. Results show that the problem of temperature control in synthesis would be modified by means of continual addition of B powder, the Li_7B_6 would be more finely distributed in the metal Li by means of intensified stirring. The discharge characgeristic of the Li-B alloy using amorphous B as starting materials is almost the same with that of using crystalline B.
